# --description--

Now that the teacher has all of the information they need, they want to be able to message the student with the results.

Complete the `studentMsg` function with `totalScores` and `studentScore` for parameters. The function should return a string representing a message to the student.

If the student passed the course, the string should follow this format:

```js
Class average: average-goes-here. Your grade: grade-goes-here. You passed the course.
```

If the student failed the course, the string should follow this format:

```js
Class average: average-goes-here. Your grade: grade-goes-here. You failed the course.
```

Replace `average-goes-here` with the average of the total scores. Replace `grade-goes-here` with the student's grade.

**Tips**

- Use the `getAverage` function to get the class average.
- Use the `getGrade` function to get the student's grade.
- Use string concatenation (`+`) to build the message.
- Be careful with the punctuation and spaces in the message.

# --hints--

Your function call of `studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37)` should return the following message: `"Class average: 71.7. Your grade: F. You failed the course."`.

```js
assert.strictEqual(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37), "Class average: 71.7. Your grade: F. You failed the course.");
```

Your function call of `studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100)` should return the following message: `"Class average: 50.8. Your grade: A++. You passed the course."`.

```js
assert.strictEqual(studentMsg([56, 23, 89, 42, 75, 11, 68, 34, 91, 19], 100), "Class average: 50.8. Your grade: A++. You passed the course.");
```

Your `studentMsg` function should return a the correct message based on the student's score and the class average.

```js
assert.strictEqual(studentMsg([33, 44, 55, 66, 77, 88, 99, 100], 92), "Class average: 70.25. Your grade: A. You passed the course.");
assert.strictEqual(studentMsg([33, 44, 55, 66, 77, 88, 99, 100], 57), "Class average: 70.25. Your grade: F. You failed the course.");
```
